Distributor



Patented Oct. 21, 1930 UNITED STATES PATENT OFFICE LOUIS B. SAUER, OFWESTERN SPRINGS, ILLINOIS, .ASSIGNOR TO KELLOGG SWITCH- BOARD & SUPPLYCOMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS DISTRIBUTOROriginal application filed April 25, 1924, Serial No. 708,876. PatentNo. 1,717,854, dated June 18, 1929.

Divided and this application filed December 17, 1928. Serial No.326,647.

My invention relates to current controllers, commonly called ignitiondistributors, for the electric ignition of internal combustion enginessuch, for example, as are used in automobiles.

A feature of my invention is the provision of a distributor head foropera-tively connecting external conductors to the distributor, incombination with the provision of a protector cap for engaging thedistributor head to protect the connection of the external conductorswith the said distributor head from the elements such as dust and water.

Another feature of my invention is the provision of separate means forsecuring the distributor head of my invention to the distributor casing,and the provision of separate means for securing the protector cap tothe distributor head.

The above features, as well as others, will be pointed out more indetail in the ensuing specification and for a clearer understanding ofthe features of my invention, reference may be had to the accompanyingdrawing in which like reference characters in the several views denotelike parts, and in which:

1 is a side plan View of my invention showing the protector cap partlyin section and secured on the distributor head, and also showing themeans for securing the distributor head on the distributor casing;

This application is a division of my application for Letters PatentSerial No. 708,876,

filed April 25, 1924 and issued June 18, 1929 as United States LettersPatent No. 1,717,854.

Referring now in detail to my invention as illustrated in the drawing, Cis a cup-shaped enclosing casing for supporting and enclos ing variousparts of the ignition distributor, while DH is the distributor head andPC is the protector cap of my invention.

The protector cap PC is formed out of nonconducting material such asbakelite or the like, and comprises a substantially cap shaped member 2which has an integrally formed outwardly extending portion 3 in the formof an inverted outlet. The conductors 4 as indicated in Fig. l areconnected to the terminals of the distributor head DH as is wellunderstood and the protector cap PC, which 0 vers the distributor headprotects the dis tributor head and the terminal ends of the conductorsconnected to the terminals of the distributor from water, dust, greaseand the like. The protector cap PC is also provided with integrallyformed ears 6 for purposes as will presently be described. The protectorcap PC is adapted to fit over and engaoe the outer face of thecircumferential e Y, integrally formed with the distribr head DH, and issecured upon the said distributor head DH, by means of suitable screws8, which extend through suitable openings in the said ears 6 and havescrew-threaded engagement with suitably tapped inserts secured in themembers 10 integrally formed with the distributor head DH. Thus it willbe seen that the distributor head DH and protector cap PC are securedtogether to form a single unit.

To secure the unit comprised of PG and DH in operative position upon thecasing C spring members 12 are provided and are hinged on the members 13secured in the members 14, which members 14 are suitably secured to theside of said casing C so that said spring members 12 are diametricallyopposite each other. A pair of wing members 15 are provided which areintegrall formed with the pair of members 10 of the distributor head DH,the said wing members 15 being provided with flanges 16. The loopportions 17 .of the spring members 12 are adapted to be hooked over theflanges l6 and engage the wing members 15 whereby the flanges 16 retainthe spring members 12 in engagement with the wing members 15. Due tospring pressure exerted by the spring members 12 upon the wing members15, the protector cap PC and distributor head DH are secured on thedistributor casing C as a unit. The protector cap PC may be removed byre moving the screws 8, and the protector cap PC and distributor head DHmay be removed as a unit from the casing C by lifting the loop portion17 of the spring member 12 from the wing members 15.

Having described a preferred embodiment of my invention I do not wish tobe limited to the exact structure as shown and described, as

changes and modifications may be readily suggest themselves, therefore,it is to be un- .derstood that I intend to cover all that which may comewithin the spirit and scope of the appended claims.

Having described my invention, what I cl'aimis'newanddesire to secure byUnited States Letters Patent isng a casing, a distributor head, providedwith. integrally formed wing members, sup. ported on said casing, earsintegrally iormed with said wing members, a protective cap,
